vTOE-PIECE FOR LASTING-MACHINES.

Specification forming part of Letters Patent No. 46,375, dated February14, 1865.

T0 all whom it may concern:

Be it known that we, ABRAM SHELDON Mo- INTIRE and NATHANIEL STEVENSTHOMP- SON, both of Stoneham, in the county of Middlesex and State ofMassachusetts, have invented a new and Improved Method of Making aToe-Piece for Lasting-Machines; and we do hereby declare that thefollowing-is a full and exact description thereof, reference being hadto the accompanying drawings, and to the letters of reference markedthereon.

The nature of our invention consists in the peculiar method of formingthe toe-piece (which is done by using` a part ofthe machine and anunfinished shoe on the last for a mold) of gutta-percha or some similarsubstance in a pliable state, which becomes hard and but slightlyelastic after taking the form of the toe of the shoe. By this method atoepiece is formed which of necessity makes a perfect lit, andconsequent-ly will not injure the leather by tearing or bruising, andcan be made by any workman in one-tenth the time required to makethe'ordinary toe-piece.

To enableothers skilled in the art to make and use our invention, Wewill proceed to describe its construction and operation.l

The drawing on Sheet No. l is a perspective view of the Working modelfor molding the toe-piece. It is not intended that this model shouldrepresent in any other than a general' manner a machine for making ourtoe-piece, as we can readily mold the toe-piece Without the aid ot anyother machine than the ordinary lasting machine and a lasted shoe, asshown on photograph, Sheet N o. 2.

In the following description similar letters refer to similar parts.

Drepresents a lasted shoe.

the movement of which the toe of the shoe is lasted.

B represents a socket for holding the heel of' shoe, or that part of thelasting-machine by the movement of which the heel of the shoe is lasted;A, base or body of machine.

To mold a 'toe-piece we proceed in the following manner: The heel ofalasted shoe is placed in the socket B, the head-piece O is drawn awayfrom the toe, and the guttapercha, or other similar substance of whichwe propose to make the toe-piece, is placed in the socketF in apliablestate. Then the headpiece is moved up firmly against the lasted shoe andis held or secured in position until the material hardens. Thelastedshoe is then removed, and the toe-piece is ready for use.

In practice we find it best. to use the lasting-machine itself for amold. In this case the lasted shoe is placed in position, the jaw C isdrawn out by means of the hand-screw, and the material placed in thesocket for the toe-l piece. The jaw is then screwed up so that thepliable material .will be pressed firmly against the toe of the shoe andheld in position until the material hardens. The lasted shoe is removed,and the toepiece is ready for use.

What we claim as our invention, and desire to secure by Letters Patent,is-

The method of forming a toe-piece for lasting-machines of any suitablematerial by meansoi' the lasted shoeand the jaw of the plasting-machine, substantially and for the purpose as herein described.
